I'm having the same problem. My 2000 WJ is pushing 95,000 miles. I bought it with 20,000 miles in 2001 so i'm unaware of an issue before. The first time i had the warpage, i had the rotors turned and replaced the pads (organic). It worked well for a while. When the problem returned i replaced the rotors and pads (ceramic) which lasted longer. I have now been driving the vehicle in Italy for the past 2 years. The problem has been gradually getting worse within the last few months. After some research online. I've come to the conclusion of replacing my Teves calipers with Akebono calipers which Jeep upgraded future WJ's with in 2002. Along with a caliper replacement you have to replace the rotors as well. After some more research regarding slotted, drilled, vented rotors, i'm just going to go with stock replacements. Right now i'm trying to figure out if there's a better caliper/rotor combination before i commit to this order. As it is, it's around $500. Also, like the previous poster. Make sure you don't overtighten your lug-nuts. I don't know if that contributed to my problems. I've always used a hand 4-way type lug nut wrench. I recently read that they should only be tightened from 85-100 lbs/ft. I'm going to place the order for the parts which should arrive in about a week.

Actually i just recently found this out (to my dismay) you can't use an air wrench to tighten jeep wheels with disk breaks. it took me about 200 dollars in warped rotors to figure that one out. it's a hassle, but they dont warp if you use a breaker bar.

Simply put, dealers are not always the most honest. Warped rotors is a very serious event. They warped from heat and a fair amount of it at that. The issues causing this should have been immediately addressed.

Lathing them down is a ridiculous concept in this case. They should have sent those rotors off for a quality inspection and the issue fixed as well as your rotors replaced. Perhaps at a cost but they were grossly negligent putting lives at risk. I would consider filing a complaint and never use them again.

Take the car back and have the tires re-balanced. Also have the front brake rotors checked to see if they are warped. If your front rotors are warped it will give you a shimmying effect when you apply the brakes coming to a stop. If they are warped you can either have them "turned" to bring them true again, but sometimes the rotors are inexpensive enough to just replace because even though you turn them there is a chance they will warp again in a few days.

well first of all just because they can be turned dosent always mean that you should do it, now a days rotors are alot cheaper to just replace them, however whatch where you buy them. in most cases you get what you paid for, Like cheap rotor prices=less life, same for the pads and how hard the driver uses the pedal. and as for the "classic rotor warp" thats not always the case with these newer cars having more movable joints than ever befor, it could be, bad hub bearing,bad lower ball joint...etc....good luck

Three items that can cause that are seized caliper slide pins, frozen (partially) caliper piston or an internally failing brake hose (rubber one from body to caliper) Problem with any of these will keep caliper partially applied and will overheat and warp the rotor. Also, I recommend torquing wheel lugs when assembling...use star pattern.

Check your front brake discs (rotors) - they may be warped. Check front brake calipers - are they working? Check condition of tyres. Answer is more likely to be the rotors. Your symptoms are dangerous.
